The clearest market-moving development was the easing of immediate Strait of Hormuz risk. Reports that Iran and Oman were discussing a temporary arrangement led traders to price a lower probability of near-term disruption to energy flows, sending Brent and WTI down roughly 2% to 6% across market reports. Washington’s expanded Iran sanctions failed to offset that relief because they had not immediately impaired supply.

The cross-asset transmission was straightforward: cheaper crude reduced inflation anxiety, the 10-year Treasury yield fell roughly 2 to 7 basis points to about 4.63%-4.66%, and U.S. equities finished higher. The S&P 500 rose 0.32%, the Nasdaq gained 0.66%, and megacap technology led the advance. Gold remained elevated, however, suggesting the geopolitical risk premium was reduced rather than erased. The market’s reaction leaves future oil moves highly sensitive to whether the Iran-Oman discussions produce an operational reopening or merely delay renewed tensions.

Nvidia earnings became the decisive near-term catalyst for the AI complex and, by extension, market sentiment. Semiconductor shares recovered part of a prior decline exceeding 3%, while megacap technology helped the Nasdaq outperform the Dow and S&P 500. The setup reflects unusually concentrated expectations: investors are looking to Nvidia’s results and outlook for confirmation that AI infrastructure demand remains strong enough to sustain the sector’s premium valuations.

The day’s broader technology headlines—continued focus on AI hardware and infrastructure, Victory Capital’s $7 billion agreement to buy First Eagle, and Vanguard’s $4 billion purchase of Altruist—were secondary to the earnings event. Crypto and tokenization initiatives in Asia, including possible progress toward Bitcoin and Ether ETFs in Thailand, added to the digital-assets narrative but did not drive the main equity move. Nvidia’s guidance now matters less as an isolated corporate update than as a read-through for semiconductors and the market’s dominant growth trade.

The second estimate of U.S. Q2 GDP held growth at a 1.5% annualized rate, below Q1’s 2.1%, while upward revisions to consumer spending and business investment showed that the slowdown remains orderly rather than abrupt. That resilience supports risk assets, but it also limits the urgency for policy relief. PCE inflation remained elevated at 3.7% year over year, with core PCE at 3.3%, unchanged from June.

The policy message was similarly uneven internationally. Brazil cut the Selic by 25 basis points to 14.00%, its fourth consecutive quarter-point reduction, while leaving further moves data-dependent. ECB Governing Council member Isabel Schnabel argued that euro-zone rates still need to rise because of upside inflation risks. Australia’s hotter-than-expected 3.5% CPI increased expectations for another RBA hike, and accelerating Japanese service-price inflation strengthened the case for a possible BOJ increase next month. The result is a market-friendly growth backdrop constrained by persistent inflation and limited room for broad-based easing.

Trade diplomacy supplied a distinct, if less immediate, geopolitical risk. Washington was reportedly weighing further measures against Canada after Ottawa’s retaliation, while Canadian Prime Minister Mark Carney was scheduled to address European Union allies under pressure from the Trump administration. Unlike the Hormuz headlines, this dispute had no clear same-day cross-asset shock, but it extends uncertainty around North American trade policy.

The contrast matters for markets: energy relief supported the day’s rally, while trade measures remain a potential source of renewed inflation and growth pressure if they escalate. For now, investors treated the Canada headlines as a background policy risk rather than a reason to reverse the equity and bond response to lower crude prices.
